Zenfone 5z comes with SD845 and it can be stable with Android 11. So, we (Zenfone 5Z users) all request you to come with an update which provides Android 11 and ZENUI 7.
Chances of getting A11/Zenui7 is almost zero. As it already received 2 promised os upgrades.
But still you can request here 👇in this thread
If not Android 11,then 5z atleast deserve ZENUI7.
